Re: vscan permission denied

Confused.

Your server hostname is 'linux01.mydomain.com', if you have 'vscan' in /etc/postfix/aliases, and mail sent to 'root' is forwarded to "me@mydomain.com" in /etc/postfix/aliases, all emails sent to 'vscan@linux01.mydomain.com' should be forwarded to "me@mydomain.com".

Did you try to generate new email sent to 'vscan"? Was it delivered to 'me@mydomain.com'? You can try it with below command:

# mail -s "test" vscan < /etc/hosts

It will send an email to 'vscan' user, with subject "test", mail body is file content of /etc/hosts.
